How
to
Add
Coolant
to
the
Radiator
...........
.
.....
1.
You
can remove
the
radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper
radiator
hose,
is
no longer hot.
Turn the pressure cap slowly counterclockwise until
it first stops. (Don’t press down while turning the
pressure cap.)
If
you
hear
a
hiss,
wait
for
that to stop.
A
hiss
means there is still some pressure left.
